this is a simple almost complete example:
// Code start:
using System;
namespace ParentPropertyExample
{
public class RTLComponent : System.ComponentModel.Component
{
private System.Windows.Forms.Control _parent;
private System.Windows.Forms.RightToLeft _rightToLeft;
private bool _inheritRightToLeft;
public RTLComponent()
{
}
public RTLComponent(System.Windows.Forms.Control parent)
{
this.Parent = parent;
}
public System.Windows.Forms.Control Parent
{
get
{
return _parent;
}
set
{
if (_parent==value)
return;
if (_parent!=null)
_parent.RightToLeftChanged-=new
EventHandler(this.ParentRightToLeftChanged);
_parent = value;
_parent.RightToLeftChanged+=new
EventHandler(this.ParentRightToLeftChanged);
if (this.DesignMode)
return;
if (!_inheritRightToLeft)
return;
if (this.Parent==null)
this.RightToLeft = System.Windows.Forms.RightToLeft.No;
else
this.RightToLeft = this.Parent.RightToLeft;
}
}
public System.Windows.Forms.RightToLeft RightToLeft
{
get
{
return _rightToLeft;
}
set
{
if (this.DesignMode)
{
if (value==System.Windows.Forms.RightToLeft.Inherit)
_inheritRightToLeft = true;
else
_inheritRightToLeft = false;
}
_rightToLeft = value;
}
}
private void ParentRightToLeftChanged(object sender, EventArgs e)
{
if (this.DesignMode)
return;
if (!_inheritRightToLeft)
return;
if (this.Parent==null)
this.RightToLeft = System.Windows.Forms.RightToLeft.No;
else
this.RightToLeft = this.Parent.RightToLeft;
}
}
}
// code end
talk to me again if it is not clear - have no time to explain right now -

Ok thanx, but how can I implement a parent property?

I see.
I probably misunderstood you.
A Component has no Internal RightToLeft support. I thought you were
talking
about a Control/UserControl.
If that is the case, you should implement a Parent property yourself that
implements direction control (any Control object), and then sign to its
RightToLeftChanged event.
